IMPACT WATER-WHEEL.

Application filed January 2-4, 1911.

To all whom "it may concern:

Be it known that I, JOHN KINoAn), citizen of the Dominion of Canada,residing at Vancouver, in the Province of British Columbia, Canada, haveinvented a new and useful Impact Water-Wheel, of which the following isa specification.

This invention relates to an impact water wheel of that class which isexemplified by the Pelton wheel, and my improvements are directed to theprovision of a cup of such form that instead of dividing the jet andspreading it laterally from the plane of rotation, it will deliver itfrom one side or the other of the wheel and in reversing its directionof movement will divert it inward in opposition to the centrifugalforce. By this means a greater proportion of energy of the water will bederived from it, in the further attainment of which object the inside ofthe cup is provided with a series of shallow flutes against the sides ofwhich the water will react during the lateral diversion.

The invention is particularly described in the following specification,reference being made to the drawings by which it is accompanied, inwhich:

Figure 1 is a side elevation of a segment of the wheel showing one ofthe cups in outside elevation and the other in section on the plane B inFig. 2, Fig. 2 is a plan of a cup, and Fig. 3, a transverse section ofthe cup on the line A.

In plan the outline of the cup is somewhat kidney-shaped the jet 2delivering into the end 3 in or parallel to the plane of rotation, andat an angle approximately tangential to the path of this portion of thecup. Toward the other side 4, from which the water is delivered, theoutline of the cup is turned slightly inward toward the axis of rotationof the wheel, and in the turn leaves somewhat of a spur or shoulder at 5where it turns around the rim of the wheel or disk 6 to which the cupsare secured.

The rim of the cup is substantially in one plane, save for a shortdistance at 7 where it cuts into the jet, where the cutting edge or lipof the cup is thinned to a fine edge and dips below the general plane ofthe edge.

In securing the cups to the wheel or disk the plane of the rim of eachcup is angled slightly upward from planes radial to the axis ofrotation. Thus the jet as it strikes on the side 3 will be deliveredlaterally to- Specification of Letters Patent.

ward 1 and in that movement will be thrown outward from the axis ofrotation by centrifugal force. This tendency is, in a measure,counteracted by the general form of the outer edge 8 which bends inwardtoward the axis of rotation and being cup-shaped the reaction of thisdiverted jet absorbs the energy of the water while reversing itsdirection. This reacting effort is increased by a series of sharp edgedridges 9 which follow the general conformation of the outer edge 8 ofthe cup and deliver the spread water of the jet inward toward the axisof rotation of the wheel.

As shown in Fig. 3, the curvature of the cup transversely is moreconcave at the side 3 of reception of the jet and is flattened slightlytoward the side 4: of delivery.

Where the ridges 9 spring from the side 3 of the cup they turn slightlyinward, as shown in plan in Fig. 2, before following the transversecurve.

Vhat I regard as the essential features of the invention are thedelivery of the jet on one side 3 of the cup and the conformation of thecup by which the impacting water is delivered toward the other side andinward toward the axis of rotation; and on the spur form 5 whichdeflects a portion of the spread jet outward against the inside of theridges 9 and of the outer edge of the cup at 8, and in the provision ofthe ridges 9 curving transversely inward toward the axis of rotation.

The cups may be secured to the wheel in any suitable manner and in anydegree of proximity to one another and may deliver to either side of thewheel in any one wheel, or in alternate cups, so as to balance anylateral vibration that may be set up in the wheel disk.

Having now particularly described my invention and the manner of itsuse, I hereby declare that what I claim as new and desire to beprotected in by Letters Patent, is:

1. In an impact water wheel, a cup for the reception of the water jetthe side of which cup into which the jet is received is more concavethan the side from which it is delivered the general conformation of thecup in plan curving inward toward the axis of rotation at the deliveryside.

2. In an impact water wheel, a cup for the reception of the water jetthe outer edge of the cup 111 plan curving across the plane of rotationand inward toward the axis of the wheel and a series of sharp edgedridges in the bottom of the cup following generally the same inwardcurve.

3. In an impact water wheel, a cup for the reception of the water jetthe side of which I cup into which the jet is received being approximately a spherical se ment and thereafter in plan curving inwardaround the edge of the wheel to which the cups are secured toward theaxis of rotation, and a series of cup into which the jet is received ismore concave than that to which it is delivered the plane of the rimbeing angled upward from a plane through the axis of rotation and theedge which contacts with the jet being lowered below the plane of thegeneral edges of the cup.

5. In an impact water wheel, a cup for the reception of the water jethaving ridges arranged transversely of the plane of rotation of theWheel and curved inwardly toward the axis of rotation at one side.

6. In an impact water wheel, a cup for the reception of the water jethaving ridges extending laterally from the position of impact of the jettoward the delivery edges of the cup and curved inwardly toward the axisof rotation at one side.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
